REGULATOR.

SPECIFICATION forming part ef Lettere Patent No. 780,986,1dated January 31, 1905. Application filed May 5, 1904:. Serial No..206,483.

To (Ir/ZZ 7077/0777, it n'tftl/coltce'nr Be it known that I, ALBERT W.FRANoIsa citizen of the United States of America, 'residing at Beaverfalls, in the county of Beaver and State of Pennsylvania, have-invented certain new and useful Improvements in Regulators, of which the following'is aspeciication, reference being had therein'to. the ,accompam nying drawings.

This invention has relation to regulators, and more particularly to that class which are adapted to' beused in connection-with gasburners, whereby the supply or pressure of gas may be regulated when passing into the burner.

The primary object of my invention is to provide a gas-regulator of the type `wherein the regulator `is automatically actuated by the pressure of the gas delivered tl1eretoand aims to construct a regulator ofl this type that would be 'extremely simple, having no complicated partsand therefore'being extremely unlikely to become out ot' order or in nonworking'condition.v To accomplish this, and in providing myirnproved regulator, I have constructed the same whereby it will be autokmatically*manipulated by the pressurel ofthe .gas and at all times a perfect combustion es'- l vtablished and a better light obtained.

r of the same.

With the above andother objects in. viewv reference will be had tothe accompanying drawings`,l' forming a part ofthis application. wherein like numerals of reference indicate like parts throughout the several views, in

which- Figure 1 is a top plan View of my improved regulator.

Fig. l3 isa transverse sectional View taken on the line fr: met Fig.v 2. Fig. 4 is a detail perspective view of the needle-supf porting disk used in constructing my im proved 5 ulator,

regulator. Fig. 5 is atop plan View of a modi- -ied form of needle-valve.- Fig.l6 is a side elevation of the same. Fig. 7 is atop plan viewof another modified form of needle-valve, and'Fig. 8 is a side elevation of thesame.

` In the accompanying drawings reference will first be had to Fig. 2, wherein I have shown a vertical sectional view of my improved reg all parts being shown in position there- Fig. 2 is a vertical sectional View.

in, andv the, reference-numeral 1 designates the nipple of my. improved regulator, in which is located the regulating-valve, and the lower end ofthis nipple is adapted to be secured on the gas-supply pipe 2, while the' other end of said nipple is provided with a 'screw-threaded extension 3, upon which the burner (not shown) is adaptedto be secured. The nipple 1 is provided with a .central partition 4, having an aperture 5 formed therein, and in said aperture is adapted to operate the needle of the regulator, this needle being provided with an annular rim 7, the lower end of the needle 6 forming a lug 8, which when.

the needle is in its normal position is adapted to rest upon a disk 9, which, as illustrated in Fig. 4 of the drawings, is provided with two apertures 10 10, and this disk is adapted to rest upon an annular shoulder 11, formed in said nipple, also upon the top of the gas-sup? ply pipe 2 should the same be threaded sui*- iiciently into the nipple. The shank pox-tion oi' the needle 6 is beveled upon two of its sides, as indicated at 12 12, this beveled portion extending from the end of the 'needle to within a short distance 'of the annular rim 7, and interposed between this annular rim and.

the partition 4 is a spiral spring 14, the tension of said spring being adapted to normally hold the lug 8 in engagement with the disk 9, mounted in the nipple.

In Figs. 5 and 6 I have illustrated a modilied form of needle-valvewhich I may employ in connection with the regulator, and in this 4 r85 constructiomthe sliankportion y15 of. the nce# die may be tapered upon all sides, as indicated at 16, the annular rim 7 and the `lug 8 being y 1n Figs. 7

maintained in this construction. and 8 oi' the drawings another modified form of -need le is shownlwherein the tapered grooves 17 a're formed in the sides of the needle, these y,grooves being arranged diametrically opporoo from whence it ows around the edge of the same and to the aperture 5, at which point the supply of gas is regulated. To provide means whereby this is accomplished, I have beveled the sides of the piston, as indicated at 12 12, and upon the pressure of the gas overcoming the tension of the spring 14 the needle 6 will be raised by the gas striking the under face of the annular rim 7 and the needle will be raised suiiiciently to close the opening 5, whereby an equal amount of gas will pass through theA same as it' the pressure had not been increased, and upon the gas resuming its normal pressure the spiral spring 14 will expand and lower the needle to its normal position, whereby the normal pressure of gas will be permitted to iiowv through the opening of the partition 4:.

It is a well-known fact that the pressure of gas in supply-pipes varies, and this varying of the pressure tends to produce a flickering and unreliable light, and in constructions of burners in which a mantle is employed it often serves to cause thebreaking of the mantle,

and thus impairs the electiveness of the light. This objectionable feature is entirely oyercome by the aid of my improved regulator,

as by itsuse the pressure of the gas is constant or normal, any increase of pressure. in the line being compensated for by the regu- 'lator partly closing the discharge-orifice to -the burner, whereby a constant pressure or n quantity of gas is delivered to thie burner.

The many advantages of my improved regulator will be apparent from the foregoing description, taken in connection with the operation, and while I have herein shown the preferred form of ,construction it is` observed that either one of the modified forms of needle may be readily'y used in place of the preferred form of constructing the needle, and very slight changes may be made without departing from the general spirit and scope of the invention.

Having described my invention, what I claim/as new, and desire to secure by Letters Patent, is-

1. In an automatic gas-regulator, a nipple provided on its upper end with an extension and having an interior partition provided with a central opening, a perforated'disk mounted within the nipple and free to move vertically therein, means for supporting said disk, a needle resting on the disk, and projecting into the central opening of said partition, and means between the partition and the disk for normally holding the latter stationary.

2. 1n an automaticgas-regulator a nipple having a threaded extension on its`upper end and provided with 'a partition having a ccntral opening or discharge-orilice, an interior annular shoulder in said nipple forming a seat, a perforated disk resting normally on said seat and free to move vertically in the nipple, a grooved needle resting on the disk and projecting into the central. opening in the'partition, an annular flange carried by said ncedle at a point slightly above its lower end, and a spring interposed between the partition on the said flange, substantially as' described.

3. In an automatic gas-regulator a nipple having an extension on its upper end, and provided with a partition having a discharge-orifice, a perforated disk supported within the nipple and having free vertical movement therein, a tapered needle supported on the disk and extending into the discharge-orifice of the partition, a fiange or rim on said needle at a point slightly above its lower end, and a spring arranged between the partition and said flange or rim, substantially as described.

In testimony whereof I afiix my signature in the presence of two wltnesses.

ALBERT W. FRANCIS.
